Q: My iPhone 6s home button is really hot and the device won't turn on

And chalk another one up.  6s pre-ordered, received on launch day - 64gig on Verizon, Samsung processor.  No problems up until now.  Just had it sitting on my desk.  Screen was blank, and I hit the button to unlock and nothing happened.  Tried to power it on and no response, and felt that the button was warm.  Showed it to my boss who tried it, but didn't think it was warm.  He did a hard reset and it came up.  I did some searching online and found this thread.  Kind of a bummer.

I also had this problem! Now, after a reboot, it works again. But I was panicking so hard!! I really don't appreciate that! -.-

glad to see so many other people have the same issue. My 6s plus had exactly the same problem last night. When I called the tech support, I was told that was not a common problem. I did not buy the extended warrant, but now I think maybe I should.

My apologies if this has already been mentioned. I didn't read all of the posts.

Some protective cases can have an insulating effect on your iPhone and lock in heat.

In my opinion, it is not a good idea to habitually leave your phone plugged in overnight to charge. If this is done with a case that locks the heat it, it will cause your phone to overheat.

Prolonged heat exposure will damage the lithium ion battery in your phone and shorten its life span and ability to retain a charge.

Lithium batteries (in smartphones and laptops, for example) function optimally with frequent small/partial discharges and charges rather than being completely discharged then completely charged.

Same thing just happened to my phone- 6s 64g not the Samsung processor so that seems to rule out that theory. Phone  was not plugged in, just on bedstand overnight. About 85% battery so it didn't seem to drain it. But did have to sign in to everything again (is that because of the soft reset?) Case is simple one which is identical to the one I used on my 5s with never an issue. Running 9.0.2.

Most consistent thing I can see running through this thread is that is seems to happen most often when owner of phone is asleep so folks- perhaps this will be the fix. Do Not Sleep. (yes- just a little lightening joke).

Bit disconcerting since I am taking it overseas for a month leaving in a week and it is my contact and my camera and my alarm and my guidebook etc etc. Guess the iPad does come along.

Having the same issue. iPhone 6s 128gb running iOS 9.0.2. Happened while sleeping and noticed when my alarm didn't go off. I couldn't believe how hot the button was. My fear is that something inside fried.

Also interesting to note, my watch seemed to still be connected the entire time my phone was "dead", which was for at least 30 minutes. I tried making a call from my watch though and it failed. So I feel like the phone was still on but stuck in some overheating/screen blackout nightmare. Anyone been successful in getting their phone replaced?

Just spoke with Apple- this is a software issue which will be fixed with update coming in next week or so. They assured me that the phone is not damaged and will not heat to the point of causing a fire. Soft reset seems to work fine for me- hold home button and on/off button down until the Apple logo comes on. Getting phone replaced probably won't do anything since this is a problem that potentially could be evident in all 6s and 6sPlus phones.

Was your phone face up or face down when it happened?

My theory is that placing face down might mitigate it from happenin.

was face down. charging with apple charger overnight.

same happened to me just this morning. I was using my phone, wasn't charging, then put the phone next to my bed then went for a shower.  Got dressed and went back to the phone and phone's screen was dark and home button wasn't responsive. 

I thought the battery was drained so I pluggged it into the charger.

A few minutes later, I went back to check the phone again and the home button piece was burning hot....

looked up google and found this thread and followed what some of you guys did to hard boot the phone (lock + home button hold for 10 seconds) . I had to use a pen to hold down the home button cos the touch id ring was just so hot...

iPhone 6s 128GB silver.  iOS 9.0.2

Interesting point, my phone was facing down on some linen material when this happened first.

That's a great news if this issue can get fixed by firmware upgrades. Thanks for the update.

JUst plugging it in to my MacBook did not work; I had to hold the power/home buttons for about ten seconds and the phone "woke up"

I Got my 6s 64G yesterday from Verizon.  Setup was fine, no problem all day.  plugged in my phone to charge last night after setting my alarm. Hubby got up early, went to turn off my alarm....black screen.  Figured I hadn't plugged it in all the way and it died.  Plugged it in to my MacBook; nothing.  tried the power/home reboot (as a long time iPhone user, that usually works).  Noticed the home button was really hot but the phone came on, charged 100%.
